摘要：A cold model experimental device was established for studying droplet entrainment in the composite scrubbing-cooling chamber. The effect of the superficial gas velocity, the initial liquid flow velocity of the nozzle, and the radial position of nozzles on droplet entrainment was investigated. The experimental results show that the droplet entrainment increases with the increase of the superficial gas velocity and the flow rate of falling film, but its profile is quite mean in the radial direction in the chamber. The droplet entrainment decreases by about 40% when the number of nozzles increases from two to four. Increasing the nozzle number can make the droplet well distributed and reduce droplet entrainment. Based on the experiment data, an empirical correlation for droplet entrainment fraction is also obtained, as E proportional to Re-1.92 .We(0.52). The optimization study for the structure of the scrubbing-cooling chamber can provide some guidance for the industrial application. (C) 2017 Curtin University of Technology and John Wiley & Sons, Ltd.
